Title: Semiconductor laser device
Inventor: IKEDA SOTOMITSU
IPC: H01S5/00
Filed: 1989-03-31
Abstract: PURPOSE:To perform multi-wavelength light oscillations having uniform threshold gain by forming an active layer of a plurality of quantum well layers having different energy gaps, and reducing the well width of a high energy gap smaller than that of a low energy gap. CONSTITUTION:A quantum well structure of an active layer is made of a plurality of quantum well layers 52, 54 having different energy gaps and light and electron confinement layers 51, 55. The layer 52 having larger energy gap is smaller in thickness (lateral width of its well) than the layer 54 having smaller energy gap, and can be oscillated in lower threshold current density than oscillation of the layer 54 having the same energy gap and large thickness. Thus, the layers 52, 54 can be formed to have gain in any wavelength by junction of a current from an exterior, and the wavelengths can be oscillated with the injecting currents of the same degree.
